#12259 — Bug#949187: transition: python3.8

Please can this wait until the remaining bits of the libffi7 transition
and the restructuring of the libgcc_s packaging have settled down?

I'm still trying to sort out the missing Breaks around
gobject-introspection, as highlighted by autopkgtest failures: this has
been delayed by needing coordinated action between multiple packages,
some of them quite big (glib2.0), and by Paul and I being at FOSDEM.
This is entangled with python3.8 via pygobject (which will fail tests
with python3.8 as default - an upload is pending to fix that).

Meanwhile, multiple packages seem to FTBFS on s390x with the new libgcc_s
(I've just opened the bug for that, so no bug number known yet), which is
going to limit the ability to get things into testing.

Thanks,

Yeah, gobject-introspection was actually what I meant when I wrote
"fontforge". My bad, bad memory....

in a sid chroot with python 3.8 as default:

root@frodo:/# python3 --version
Python 3.8.1
root@frodo:/# g-ir-scanner 
Traceback (most recent call last):
  File "/usr/bin/g-ir-scanner", line 99, in <module>
    from giscanner.scannermain import scanner_main
  File "/usr/lib/x86_64-linux-gnu/gobject-introspection/giscanner/scannermain.py", line 35, in <module>
    from giscanner.ast import Include, Namespace
  File "/usr/lib/x86_64-linux-gnu/gobject-introspection/giscanner/ast.py", line 29, in <module>
    from .sourcescanner import CTYPE_TYPEDEF, CSYMBOL_TYPE_TYPEDEF
  File "/usr/lib/x86_64-linux-gnu/gobject-introspection/giscanner/sourcescanner.py", line 33, in <module>
    from giscanner._giscanner import SourceScanner as CSourceScanner
ModuleNotFoundError: No module named 'giscanner._giscanner'

and thus stuff building introspection will FTBFS (right now)

(Thus I needed to disable it in my testbuild and thus 

libreoffice (1:6.4.0~beta1-4) experimental; urgency=medium

  * re-enable introspection which was accidentially kept disabled after a
    python3.8 test rebuild...
  * re-enable building of the "test packages"
    (-smoketest-data, -subsequentcheckbase)

happened.)

This is fixed in 1.62.0-5 (#950267). Upload was delayed by FOSDEM, needing
a glib2.0 upload to be built first (to have the right Breaks for the libffi7
transition to avoid autopkgtest regressions), and me being unwell.

Thanks, yes, that prevents the install of the "old" gobject-introspection with the new python3 from experimental.

Sorry, I wasn't thinking straight (I blame post-FOSDEM illness). That
isn't actually what you need if you want to port to python3.8 - it won't
support python3.8 until the binNMUs for this transition happen. If you
need a python3.8 version of gobject-introspection before then, you could
maybe NMU it into experimental?

I *think* Build-Depends: python3-dev (>= 3.8) should do what you'd need,
but don't necessarily trust my technical judgement right now!

Actually, no, I just wanted to prevent it FTBFSing when the default
changes and gobject-introspection wasn't yet rebuilt.

LibreOffice also only builds dor the default. (With a shitload of
hackery it is possible to build pyuno twice/thrice etc. but given
there*s a LO part of it this will not be coinstallable, defeating the
purpose.)

Regards,

Rene
